A highlighted sentence is not yet a useful note. It becomes useful when you can find it again, understand why you saved it, and connect it to something you are working on. The technical challenge is usually less about capturing more text than preserving enough context as that text moves between tools.
The design I recommend is deliberately boring: read a file, export highlights to Markdown, add interpretation, and keep the resulting notes in an ordinary folder. Obsidian can make that folder pleasant to navigate. Git can record its history. Neither needs to become the only place the notes can exist.
Here is a pipeline you can build without designing an elaborate personal knowledge-management system first.
Start with two kinds of material: the book you are reading and your notes about it. Keep them separate. A purchased or otherwise lawfully obtained EPUB belongs in your reading collection; your observations belong in your notes folder.
